Bug in block length when using arbitrary RF pulses or gradients #38

Closed Mmj94 closed 2 years ago

Mmj94 commented 3 years ago

Describe the bug Sequences won't play when any of the blocks have arbitrary RF or gradients with the same length. Based on trial/error experiments, seems like the gradient waveforms have to have a slightly longer duration compared to the other components of the block (RF pulse signal, adc).

To Reproduce Create an arbitrary gradient waveform using make_arbitrary_grad Design ADC to have the same number of samples as the gradient created seq.add_block(gradient,adc)

Expected behavior The sequence won't play with the last version of the interpreter.

Hi @Mmj94! Is this still an issue?
